The SARS-CoV-2 virus is a respiratory pathogen that causes severe acute respiratory syndrome (SARS) disease. It can be transmitted from person to person through close contact, particularly when an infected individual coughs or sneezes.
Although vaccines provide a strong defense against severe illness caused by SARS-CoV-2, none fully protects against the infection, meaning many vaccinated people are still at risk of catching the virus and of transmitting it to other people. The more SARS-CoV-2 is circulating in a community, the greater this danger becomes for everyone who lives there—including those who have been vaccinated.
Here are some reasons why a vaccinated individual can still contract the SARS-CoV-2 virus:
The fact that people feel well for the first few days after infection is one of the reasons Covid-19 has spread so swiftly across the globe. People may be going about their business rather than remaining in bed, spreading viruses unintentionally. In addition to these pre-symptomatic patients, a more mysterious group of individuals is known as asymptomatic.
It’s always been conceivable that someone might contract asymptomatic cases of COVID-19 after being vaccinated, but they would be less likely to require hospitalization and die as a result of the illness.
Another reason why vaccinated people become infected is because of these so-called “breakthrough infections,” which have raised doubts about vaccine effectiveness. Data from some countries with high vaccination rates now show that vaccinated people have more weekly COVID-19 cases than unvaccinated people.
It can be confusing because as the number of people vaccinated rises, the number of cases among fully vaccinated people rises as well, even though the number of cases is much lower than it would have been if the vaccination rate had not been so high, and the proportion is much lower.
In some countries, people who are fully vaccinated are also a little more likely to become infected because they are given more freedoms than their unvaccinated counterparts.
Another factor is that the new COVID-19 delta variant has 1000 times the viral concentration in a sick person’s mouth and nose as the previous COVID-19 variant. This implies that if droplets from an infected person’s mouth or nose land in the mouth or nose of another individual, the latter is considerably more likely to get sick.
People should not be alarmed because they have received their vaccination shots; instead, they should take extra precautions such as avoiding close contact with sick people, coughing or sneezing into their elbow rather than their hands, and washing their hands frequently with soap, and water or an alcohol-based sanitizer.
And COVID-19 vaccines, which have proven to be highly effective in preventing severe COVID-19 infections that result in hospitalization and death. Despite being vaccinated, it has always been possible for someone to contract an asymptomatic case of COVID-19; however, they would be less likely to require hospitalization and would be less likely to die from the disease.
The COVID-19 vaccine is an example of how doctors have responded to a conceivable pandemic. While you can be confident that these vaccines are safe and effective, we should be cautious as new virus variants emerge. When possible, maintain social distance by avoiding indoor group gatherings and wearing masks when indoors and around large groups.
