![]() ![]() More than a month after the first vaccines for COVID-19, many people still have questions regarding what happens after receiving the full dose. Always refer to uab.edu/uabunited for UAB's current guidelines and recommendations relating to COVID-19. “This does not mean the vaccine is ineffective. It just means for the best protection of the public, a change in the vaccine is warranted.Editor's Note: The information published in this story is accurate at the time of publication. “For at least the near future, it appears yearly updates to the vaccine will continue” much like annual flu vaccines, Brian said. So far, the COVID-19 vaccines have needed to be updated to remain effective against variants. When that happens, the immune system shuts down the virus before any damage is done.” “Your body then remembers what to do if it encounters pathogens from that disease in the future. Those antibodies mount a defense against the disease for which you’ve been vaccinated,” he said. “In general, vaccines work by allowing your own body to produce antibodies. Vaccines are meant to protect you from getting seriously ill, not prevent you from becoming infected. It’s important, Brian said, to remember how vaccines work. People who are up to date on COVID-19 vaccines are much less likely to experience severe symptoms. “Breakthrough infections still happen, but they tend to be less severe than if a vaccine was never given.”ĬOVID-19 vaccines help protect against severe illness, hospitalization and death. “This will not completely prevent getting COVID though,” Brian said. Getting vaccinated is still recommended for the vast majority of the population. “It is possible to spread the infection without realizing it. As more research is done on the virus, other signs or symptoms may be discovered.” Vaccinations are key “And asymptomatic COVID infections – when someone doesn’t experience any symptoms – still happen,” Brian said. They should wear a mask and practice other precautions. People who are immunocompromised and are vaccinated still are at high risk of severe illness or hospitalization due to COVID-19. ![]() “Very few things in medicine have a 0% chance of happening,” Brian said. So can vaccinated people spread COVID to a friend or family member who is not vaccinated? It can happen. If the viral load is significantly less due to vaccination, there’s less risk of transmitting the virus to others. Viral load means the amount of virus an infected person produces. But they still can pass it on to someone else, Brian said. Vaccinated individuals have a lower viral load if they get infected. Can you be a carrier of COVID after vaccine? In these instances, however, symptoms often are mild and the individual doesn’t require medical care or hospitalization. “Their level of risk depends on mask wearing, amount of time spent around other people and whether they’re vaccinated.” “Breakthrough infections – getting COVID after a vaccine – are relatively common with COVID-19,” Brian said. Centers for Disease Control and Prevention (CDC) shows COVID-19 breakthrough cases occur in fully vaccinated people. That is an incredibly short period of time when compared to other viruses.”ĭata from the U.S. “It’s only been identified for three and a half years. “We are still learning about the virus as it changes,” Brian said. Scientists continue studying how the vaccine can prevent you from spreading COVID and becoming reinfected. Chances of getting COVID after being vaccinated “Vaccinated people can become infected with COVID-19 and spread it to others. However, a 2023 study found that vaccinated people were significantly less likely to transmit the virus,” said Brian Laird, PharmD, a manager in Pharmacy Operations at OSF HealthCare. Can you get COVID after being fully vaccinated? And can you spread COVID if you are vaccinated? There are two big questions many people about COVID-19. This article was updated July 5, 2023, to reflect new information from the CDC. ![]()
