If and when the level of neutralizing antibody that correlates with protection against SARS-CoV-2 is identified, more will be learned about how natural and vaccine-derived immunity may compare.ДЄdditionally, the authorized COVID-19 vaccines may provide protection against many well-described SARS-CoV-2 variants.

6 Data from the phase 3 vaccine trials and vaccine effectiveness studies will help to understand how well COVID-19 vaccines provide long-term protection. 5 Because of these data, vaccination is recommended for individuals who have recovered from COVID-19. 4 Although they remain rare, cases of reinfection have been reported. A recent analysis that assessed the 4 major types of immune memory found substantial durability 6 months after natural infection. Researchers are still investigating how long protection from natural infection or vaccination lasts and how well the vaccines protect against emerging SARS-CoV-2 variants. Collectively, these findings demonstrate that vaccination has the potential to substantially reduce the COVID-19 disease burden in the US.ДЄlthough scientists have already learned a great deal about SARS-CoV-2 and how well the authorized COVID-19 vaccines perform, some questions remain.

3 Viral load has been identified as a key driver of transmission and this observation may indicate reduced transmissibility. 3 More specifically, studies from Israel demonstrated that the Pfizer-BioNTech COVID-19 vaccine was 90% effective against asymptomatic infection, and vaccinated people who developed COVID-19 had a substantially lower viral load than unvaccinated people. Studies from the US, UK, and Israel found that 2 doses of Pfizer-BioNTech or Moderna vaccines were 86% to 92% effective against asymptomatic and symptomatic SARS-CoV-2 infection. In addition, preliminary but rapidly increasing evidence suggests that fully vaccinated people likely pose little risk of transmission to unvaccinated people. 3 Even if fully vaccinated people do become infected, they are much less likely to develop severe disease, be hospitalized, or die. Current data demonstrate that the authorized COVID-19 vaccines are efficacious among adults of different ages, races, and ethnicities, and among those with underlying medical conditions. When creating this guidance, the risks to both vaccinated and unvaccinated people were considered. 2 These recommendations represent the first step for individuals in resuming their prepandemic lives. With the number of people vaccinated each week continuing to increase, the Centers for Disease Control and Prevention (CDC) has released its initial public health recommendations for fully vaccinated people (individuals who are at least 2 weeks out from having received their second Pfizer-BioNTech or Moderna vaccine dose, or from their Janssen single-dose vaccine). Since then, 2 additional COVID-19 vaccines, Moderna and Janssen (Johnson & Johnson), have received Emergency Use Authorization in the US and, as of March 8, 2021, more than 31 million people, or 9.4% of the total population, have completed a vaccination series. On December 11, 2020, the US reached an extraordinary milestone in the efforts to end the COVID-19 pandemic: the Food and Drug Administration authorized emergency use of the first COVID-19 vaccine, manufactured by Pfizer-BioNTech.
