• COVID-19 vaccines are safe and effective.
• It usually takes two weeks after full vaccination for the body to build protection (immunity) against the virus that causes COVID-19.
• You may have side effects after vaccination, but these are usually expected as with other vaccines.
• Those who have been fully vaccinated can start doing some things again that they had stopped due to the pandemic.

What we don’t know yet

• We don’t yet know to what extent the vaccine prevents the spread of the virus that causes COVID-19, even when someone is asymptomatic.
• We also don’t yet know how long the vaccine protects us. vaccine against COVID-19, although the chances of protecting the vaccinated person for more than 8 months are very high.
• We still do not know how many people need to be vaccinated against COVID-19 to be considered protected (herd immunity).
• We still do not know how effective vaccines are against all new mutations of the virus that causes COVID-19.
• Although COVID-19 vaccines are effective in preventing you from getting sick, scientists are still learning to what extent the vaccine can prevent the transmission of the virus that causes COVID-19, even when someone is asymptomatic. Early evidence suggests that vaccines do prevent asymptomatic spread of COVID-19, but the more people get vaccinated, the more we learn.

Effectiveness

What we know

Studies show that COVID-19 vaccines are effective in preventing you from getting the disease. The COVID-19 vaccine will also help you not get seriously ill if you do get infected with the virus that causes COVID-19.

The COVID-19 vaccine is an important tool It usually takes two weeks after vaccination for the body to build up protection (immunity) against the virus that causes COVID-19. This means that it is possible for someone to be infected with the COVID-19 virus before or shortly after vaccination and then get sick because the vaccine has not had enough time to provide protection. A person is considered fully protected two weeks after the second dose of vaccines.

You should continue to use all available means to protect yourself and others until you are fully vaccinated. Once you are fully vaccinated, you may be able to start doing some things that you had stopped doing because of the pandemic.

What we don’t know yet

For these reasons, until we know more, those who have been fully vaccinated should continue to take precautions in public places, such as wearing a mask, staying 1-2 meters away from others, avoiding crowds and poorly ventilated areas, and washing their hands frequently.

Safety

After getting vaccinated against COVID-19, you may experience some side effects. These are normal signs that your body is building up protection. Side effects from the COVID-19 vaccine, such as chills or fatigue, may affect your ability to perform daily activities, but they should subside within a few days.

Herd immunity

What we know

Herd immunity means that a sufficient number of people in a community are protected from a disease, either because they have already had it or because they have been vaccinated.

Herd immunity makes it difficult for a disease to spread from person to person. It even protects those who cannot be vaccinated, such as newborns or those who are allergic to the vaccine. The proportion of people who need to be protected to achieve herd immunity varies depending on the disease.

What we don’t know yet

We don’t yet know how many people need to be vaccinated against COVID-19 before the majority of the population can be considered protected.

New Variants

What we don’t know yet

We are still learning how effective vaccines are against new mutations of the virus that causes COVID-19.

Early evidence suggests that vaccines may work against some mutations, but could be less effective against others.

We are learning more every day about the characteristics of new mutations.
