FAQ vaccine against Covid-19

Answers to common questions about vaccination against Covid-19.

About the vaccines

  • A vaccine approved for use in Sweden may be only one of several ways to protect yourself against Covid-19. However vaccine will not be the only solution. Even if a vaccine becomes available, you still need to think about protecting each other from infection by continuing to stay home if you show symptoms, keeping your distance, maintaining good hand hygiene and working from home whenever possible.

  • ​​​All the medications in the world are developed and tested according to the same principles; first in a laboratory environment through, for example, tests on culture in test tubes, stability tests and animal experiments. Then follow clinical trials in different phases on humans according to special requirements. All medications are tested on the patient group for which they are intended. Read more about vaccine development on the Swedish Medical Products Agency website.

  • ​​Medicines and vaccines are approved on the basis that the benefit must be significantly greater than the risk of serious side effects for their intended use. An approved vaccine is judged to be sufficiently safe. All treatment with drugs carries a certain risk of side effects and therefore it is important that all suspected side effects are reported.

  • Data and experiences from the worldwide vaccinations carried out thus far suggest that the vaccines are effective against the virus variant first discovered in the UK. There is not yet sufficient data to say with certainty whether and how the vaccines' effectiveness is affected by other new virus variants of particular importance. The initial results from laboratory analyses show that the vaccine has an effect, but we do not yet know the strength of the protection. Studies of the vaccination effect on other currently known virus variants of particular importance are ongoing.

  • ​The most common side effects of vaccination are local side effects at the injection site (tenderness, swelling, redness) but also muscle aches, fever, headache and malaise. These are a natural reaction of the body's immune system. They are usually mild and disappear after a few days. Information on common, uncommon and rare side effects can be found in the medication package leaflet for each vaccine. All treatment with drugs carries a certain risk of side effects. Medicines and vaccines will only be approved if the benefit is significantly greater than the risk in its intended use.

Before the vaccination

  • By getting vaccinated, you can protect both yourself and others. COVID-19 is a highly contagious disease that can make you severely ill. Even if you personally only contract a mild variant of the disease, other people are at high risk of becoming severely ill. Vaccination protects you from getting ill and also reduces the risk of you infecting others. It helps reduce the spread of infection across society in the long term, which is necessary in order for us to return to normal life. The approved COVID-19 vaccines provide a high degree of protection against serious illness. After vaccination, the body's immune system builds up protection against COVID-19. It is not certain that everyone who gets vaccinated will receive complete protection. However, if you do get ill, you will most likely have a milder form of the disease. In Sweden, vaccination against COVID-19 is voluntary and free.

    Källa: Folkhälsomyndigheten | 14 Apr 2021 15:12
  • Yes. All vaccinations are voluntary in Sweden, including Covid-19 vaccination. If you are offered a Covid-19 vaccination, you will be able to decide for yourself, based on available knowledge about the illness and the vaccine. You will also receive information about the vaccine before you have to make a decision.

  • At present, Covid-19 vaccination is offered to people who are 18 and older, according to Swedish Public Health Agency recommendations. Those who are most at risk of becoming seriously ill are offered the vaccine first. Initially, vaccination is not offered to people who are 17 or younger or pregnant. However, the situation may change as knowledge levels increase. Depending on the vaccine and the underlying medical problems, vaccination may, in special cases, be discussed with the individual's doctor.

  • The Public Health Agency of Sweden has produced recommendations for the order in which different groups are to be vaccinated against Covid-19. The schedule for Covid-19 vaccinations also depends on when the vaccines are delivered to Sweden.

    The Regions are responsible for carrying out the vaccinations. Go to www.1177.se and read about who is being vaccinated in your Region right now. Make sure you choose your own region.

  • Sweden is part of an agreement between the EU Commission and several vaccine manufacturers to buy Covid-19 vaccines. Sweden therefore has access to the vaccines at the same time as other EU countries.
    In Sweden, the Swedish Public Health Agency then distributes the vaccines to the Regions. This distribution is currently based on the proportion of older people living in the different regions. As we enter other phases of vaccination, other factors will control the distribution. The Regions are responsible for vaccinating the population in accordance with Swedish Public Health Agency recommendations. Read about deliveries of vaccines here.

  • The vaccines used against COVID-19 must be safe to use. Therefore, all vaccines and possible side effects are continuously monitored. In Europe, Astra Zeneca's vaccine has been administered in over 20 million doses. A small number of cases of younger people with blood clots in combination with bleeding after getting vaccinated have been reported. Therefore, the Public Health Agency of Sweden decided to temporarily suspend the use of Astra Zeneca's vaccine while the European Medical Agency (EMA) investigated whether there was a causal link. The Public Health Agency of Sweden has reviewed EMA's investigation, conducted its own review of the information available regarding the suspected side effects, and had meetings with experts in Sweden and other countries. The assessment is that for people aged 65 and older, Astra Zeneca's vaccine is safe to use and provides very good protection. For them, the vaccine may continue to be used. With respect to younger people, the temporary suspension continues while it is investigated whether or not the incidents with blood clots in combination with bleeding in younger people are linked to the vaccine.

  • After a thorough evaluation, the Public Health Agency of Sweden recommends that Astra Zeneca's vaccine should continue to be offered to people born in 1956 or earlier, meaning people aged 65 years and older. No serious side effects have been reported among people in this age group. At the same time, people aged 65 and older are most at risk of becoming seriously ill and dying from COVID-19. Astra Zeneca's vaccine provides very good protection against serious illness. Therefore, the Public Health Agency of Sweden deems it safe and important to use Astra Zeneca's COVID-19 vaccine for this age group.

  • No. We still lack knowledge about how much and what type of antibodies are required to be immune to Covid-19. Everyone will therefore be offered a vaccination, regardless of whether they have had the illness or not. Based on previous experience from vaccinations, there is no reason to believe that being vaccinated has any negative effects if you have already had the illness.

    Källa: Folkhälsomyndigheten | 12 Mar 2021 13:55
  • Yes. We recommend vaccination for everyone who has had Covid 19, including those who have antibodies. Most people who have had covid-19 have developed some form of protection against the disease, but today we do not know how long this protection lasts. You can be vaccinated as soon as you have fully recovered from Covid 19.

  • Generally, children are not currently offered vaccination against Covid-19 as the approved vaccines have not yet been fully tested on children. As knowledge develops, this may change. Children are defined as people up to and including 17 years of age. For children who are at risk of becoming seriously ill with Covid-19 because they have an underlying condition, the child's doctor may make an individual assessment. If the doctor considers that the vaccine can be of great benefit in protecting the child from serious Covid-19 infection, vaccination may be offered.

  • ​Different government agencies are responsible for different issues. The Swedish Medical Products Agency is responsible for studying medicines and making decisions on approval of vaccines and for following up safety and efficacy when the vaccines have been rolled out. The Swedish Public Health Agency is responsible for recommending who should be vaccinated. The health service in each region is responsible for carrying out the vaccinations.

After the vaccination

  • Yes, it is important that people who have been vaccinated against Covid 19 continue to follow the general recommendations, even after the vaccine has started to work. Covid 19 is still spreading. We know that the vaccine protects you from becoming seriously ill.

    However, there is limited knowledge about the risk of infecting others with the Covid 19 virus if you become ill yourself after being vaccinated. There may be a certain risk that you can then infect others, even if you yourself do not develop any symptoms so we must all continue to follow the general recommendations until more knowledge becomes available.

  • The Covid-19 vaccination creates protection against serious illness. The vaccine teaches your immune system how to create antibodies that protect you from the disease. However, it is not certain that everyone who is vaccinated will develop full protection. This applies to all vaccines, not just Covid 19. But you still run much less risk of becoming seriously ill.

    Källa: Folkhälsomyndigheten | 19 Feb 2021 10:00
  • Depending on the vaccine you receive, different numbers of doses are necessary for good protection against Covid 19. 

    • Comirnaty (Pfizer/BioNTech): approximately one week after the final dose of Covid 19 vaccine
    • COVID-19 Vaccine Moderna: approximately two weeks after the final dose of Covid 19 vaccine
    • Vaxzevria (AstraZeneca) : approximately 3 weeks after the first dose. Individuals may not be fully protected until 15 days after the second dose.
    • COVID-19 Vaccine Janssen: the vaccine begins to take effect about 2 weeks after the single dose.

  • There is currently no national certificate or standard certificate common to all regions so the government has commissioned the Swedish Agency for Digital Administration (DIGG) to develop a common digital infrastructure for vaccination certificates. The goal is that the digital vaccination certificate will be available by the summer. Before a national solution is in place, it is the vaccinator's responsibility to issue a certificate of vaccination. At the international level, similar work is underway within the EU and the World Health Organization (WHO). The Swedish Public Health Agency and the E-Health Agency have therefore been commissioned by the government to coordinate Swedish participation in digital vaccination certificates at EU level and in the WHO. Read more about the digital vaccination certificate project on the Government website.

  • There is a small risk of becoming infected even after vaccination. The protective effect after 2 doses is assessed as high in vaccine studies, but as with all vaccinations, complete protection cannot be guaranteed. It is therefore important to continue to follow the Swedish Public Health Agency advice and recommendations to reduce the risk of becoming infected or infecting others.

    Also keep in mind that it takes 1-2 weeks after the second vaccine dose, depending on which vaccine you have received, before the vaccine starts to give protection.

  • You do not need to be tested if you have just been vaccinated and you have symptoms that are typical side effects of vaccination. Examples of side effects include fatigue, fever, chills, muscle and joint pain or headaches. These side effects should disappear within 24 hours. Stay at home as long as you have symptoms.

    If the symptoms persist after 24 hours, go to the website www.1177.se/covid-19-prov and select the region you are in to see what applies to testing.
