What is the case of “breakthrough” covid-19 vaccine? That’s when people who are vaccinated are infected with Coronavirus.
A small number of cases like that is expected and health officials say they are not the cause of alarm.
The Covid-19 vaccine works by teaching the body to recognize viruses.
So if you are exposed after vaccination, your immune system must be ready to act and fight.
In the study, the Covid-19 vaccine two doses by Pfizer and Moderna were around 95% effective to prevent disease, while Johnson & Johnson’s shot shot was 72% effective, although direct comparison was difficult.
So, while the vaccine is very good at protecting us from viruses, it may still be infected with mild or no symptoms at all, or even sick.
If you finally get sick despite vaccination, experts say the photo shoot is very good at reducing the severity of the disease – the main reason for getting vaccination.
Most people with breakthrough infections have a mild disease, said Dr.
William Moss, a vaccine at Johns Hopkins Bloomberg School of Public Health.
In the US, people who are not vaccinated make up almost all hospitalization and death from Covid-19.
It is difficult to determine why certain breakthrough cases occur.
How much virus you use can be a factor, said Moss.
Our individual immune system will also affect how well we respond to shots.
Some people, for example, have health conditions or take medication that can make their immune system less responsive to the vaccine.
People might have also been exposed to the virus before the shot took the full effect.
Although it is less likely, they may have received a dose stored incorrectly or given, said Moss.
Disease control centers and prevention records can be a factor in some of the breakthrough cases, even though the evidence so far shows the vaccine used in the US protects them.
Health officials also watch signs that increased breakthrough cases, which can indicate that the protection of fading vaccines and booster is needed.
