What you need to know about COVID-19 vaccines

Vaccines save millions of lives each year and a COVID-19 vaccine could save yours. The COVID-19 vaccines are safe and effective, providing strong protection against serious illness and death. WHO reports that unvaccinated people have at least 10 times higher risk of death from COVID-19 than someone who has been vaccinated. 

It is important to be vaccinated as soon as it’s your turn, even if you already had COVID-19. Getting vaccinated is a safer way for you to develop immunity from COVID-19 than getting infected.

The COVID-19 vaccines are highly effective, but no vaccine provides 100 per cent protection. Some people will still get ill from COVID-19 after vaccination or pass the virus onto someone else. 

Therefore, it is important to continue practicing safety precautions to protect yourself and others, including avoiding crowded spaces, physical distancing, hand washing and wearing a mask.

All WHO-approved vaccines have been shown to be highly effective at protecting you against severe illness and death from COVID-19. The best vaccine to get is the one most readily available to you.

You can find a list of those approved vaccines on WHO’s site.  

Remember, if your vaccination involves two doses, it’s important to receive both to have the maximum protection. Additional doses (boosters) are recommended by the MOH for specific groups. 

Vaccines work by mimicking an infectious agent – viruses, bacteria or other microorganisms that can cause a disease. This ‘teaches’ our immune system to rapidly and effectively respond against it.

Traditionally, vaccines have done this by introducing a weakened form of an infectious agent that allows our immune system to build a memory of it. This way, our immune system can quickly recognize and fight it before it makes us ill. That’s how some of the COVID-19 vaccines have been designed.

Other COVID-19 vaccines have been developed using new approaches, which are called messenger RNA, or mRNA, vaccines. Instead of introducing antigens (a substance that causes your immune system to produce antibodies), mRNA vaccines give our body the genetic code it needs to allow our immune system to produce the antigen itself. mRNA vaccine technology has been studied for several decades. They contain no live virus and do not interfere with human DNA.

Yes, COVID-19 vaccines have been safely used to vaccinate billions of people. The COVID-19 vaccines were developed as rapidly as possible, but they all must go through rigorous testing in clinical trials to prove that they meet internationally agreed benchmarks for safety and effectiveness. Only if they meet these standards can a vaccine receive validation from WHO and MOH.

UNICEF will only procure and supply COVID-19 vaccines that meet WHO’s and MOH established safety and efficacy criteria and that have received the required regulatory approval.

Booster doses play an important role in protecting against severe disease, hospitalization and death. In terms of when to get a booster shot, particularly if you're in a high-risk group, you should follow the recommendations from MOH.

No, you may have seen false claims on social media, but there is no evidence that any vaccine, including COVID-19 vaccines, can affect fertility in women or men. You should get vaccinated if you are currently trying to become pregnant.

Some people have reported experiencing a disruption to their menstrual cycle after getting vaccinated against COVID-19. Although data is still limited, research is ongoing into the impact of vaccines on menstrual cycles.

Speak to your healthcare provider if you have concerns or questions about your periods.

The Pfizer vaccine has been approved by MOH for use in children 15 years and older.

Many countries have licensed other COVID-19 vaccines for adolescents. They’ve made them available after examining the data on the safety and efficacy of these vaccines. The best thing to do is follow MOH guidelines when it comes to what vaccines are authorized and available for adolescents.  

Remind your children of the importance of us all taking precautions to protect each other, such as avoiding crowded spaces, physical distancing, hand washing and wearing a mask. 

It is critical that children continue to receive the recommended childhood vaccines.
