Vaccines to prevent coronavirus disease in 2019 (COVID-19) are the best hope of ending the pandemic. A safe and effective vaccine could significantly contribute to the prevention of serious diseases and deaths caused by COVID-19.
Vaccines train our immune systems to recognize a targeted virus and make antibodies to fight it before we get it. Experts believe it is safer to get an RNA-CoV-19 vaccine if you are breastfeeding, but breastfeeding people are not included in vaccine trials. When a person is vaccinated during breastfeeding, their immune system develops antibodies that protect against COVID-19.
The COVID-19 vaccine, developed by Pfizer and Biontech, can effective prevent symptomatic diseases, for example, but it is unclear whether it will protect people who become infected from transmitting the virus to others. This is because clinical trials focus on vaccines that protect recipients from developing moderate to severe Covid-19.
The key to herd immunity is that an infected person has a few susceptible hosts that continue transmission so that those vaccinated who have had the infection already do not infect or transgress to others.
As a result, you may be infected with the virus that causes COVID-19 even after vaccination. It is also possible that a vaccine can protect a person from COid-19 disease, but not prevent them from becoming infected. It may be possible for a vaccine to protect against COVID, but only if the disease is prevented before a person is even infected.
Scientists study the duration of the coronavirus immunity and how likely a person is to get COVID-19. Given how new the virus is, researchers are also investigating whether vaccined people are more likely to be protected from infection and whether vaccinated people can transmit the virus on to others.
Another concern about the Covid-19 vaccine is that even if you have an asymptomatic infection before immunization, someone who has no symptoms may still be able to shake off the virus.
The COVID-19 vaccine, which is currently in use worldwide, prevents serious illness and death from coronavirus in people infected with the vaccine. Getting vaccinated helps protect people around you from the virus, as well as people who are at a greater risk of serious illness as a result of the virus.
The vaccine protects people vaccinated from getting and getting the virus again, including by reducing the risk of hospitalization and death.
