Is COVID-19 vaccination still necessary, even after getting infected with the virus and recovering?
Evidence is growing that vaccination after infection strengthens protection and further reduces the risk of reinfection. Therefore, COVID-19 vaccination is generally recommended for the eligible population, including those who have recovered from the disease.
Will COVID-19 vaccines stop the pandemic?
It is likely that SARS-CoV-2, the virus that causes COVID-19, will continue to circulate and evolve. It is not possible to predict how infectious or severe new variants of the virus will be. It is therefore very important to achieve and maintain high vaccination coverage across all communities and population groups, at national and international levels. Vaccination remains a key component of the multi-layered approach needed to reduce the impact of SARS-CoV-2.
What are the common side effects of COVID-19 vaccines? The most commonly-reported events with COVID-19 vaccines are expected vaccine side effects, such as headache, fatigue, muscle and joint pain, fever and chills and pain at the site of injection. The occurrence of these adverse events is consistent with what is already known about the vaccines from clinical trials.
Are COVID-19 vaccines effective?
COVID-19 vaccines authorised for use in the EU/EEA have been very effective at preventing severe disease, hospitalisation and death.
In general, benefits of COVID-19 vaccines may include:
- preventing SARS-CoV-2 infection in vaccinated individuals
- reducing disease severity, if vaccinated individuals are infected
- preventing death in vaccinated individuals
- reducing the number of people infected in populations with adequate vaccine uptake
- reducing virus transmission in populations with adequate vaccine uptake.
