Chief Medical Adviser to the President of the United States Anthony Fauci spoke during a recent COVID briefing. Fauci said that a fourth dose might be needed for subsets of people who had weaker immune responses. These include the elderly and the immunocompromised.
Vaccination saves lives
The World Health Organization (WHO) said in July 2021 that vaccines offer strong protection but protection takes time to build. People must take all required doses of a vaccine to build full immunity. Vaccines can take 2-3 weeks from the final vaccination to be fully effective. The WHO noted that it is important to continue all precautions during this period to protect yourself and others.
Vaccines do not provide full 100% protection, thus breakthrough infections can happen. If vaccinated people do get sick, they are likely to have milder symptoms. Vaccinated individuals rarely experience severe illness or die from COVID.
The WHO still stresses how important it is to be vaccinated as soon as possible. More vaccinations mean build building immunity in communities faster. That will then lead to a return to pre-pandemic normalcy. COVID booster efficacy may falter but that does not mean vaccination should not be a priority.
