Can a vaccinated person infect?





On December 27, the mass vaccination against him coronavirus In the countries of Europe and today the number of people vaccinated against the disease is higher than the number of new cases. However, the World Health Organization (WHO) has stated that applying the corresponding doses of the vaccine against SARS-CoV-2 is not “a carte blanche to ignore health measures such as physical distancing and hand washing.”

Currently, vaccines against Covid-19 approved by the European Medicines Agency (EMA), they are all two doses. That is, it is the second dose, the booster dose, which really increases the immune response and strengthens the immunity acquired after its application. In this way, if an infection were to occur, our body would be able to generate an effective and rapid response to prevent the disease from developing.

However, the vaccine does not mean the extinction of the pandemic virus. As the doctor indicates Katherine O’Brien, WHO Vaccine Expert “We still don’t know how long the immunity of the vaccines we have on hand at the moment lasts. We are following people who have received vaccines to find out if their immune response is long-lasting and to find out how long they are protected against the disease. So we’ll really have to wait for time to pass to see how long these vaccines last».

So what happens after getting the vaccine? It’s possible get coronavirus? And infect third parties?

Spread after the vaccine

Clinical trials of vaccines endorsed by the EMA have shown that their doses protect against development of Covid-19 disease, which can be mild, moderate or severe. However, these trials have not yielded enlightening results about whether vaccines protect people simply from being infected with the SARS-CoV-2 virus or whether they also protect against the virus. transmission of the virus to third parties.

As the namesake of Fernando Simón in the United States indicated in 2020, Anthony Fauci, director of the US National Institute of Allergy and Infectious Diseases, it is possible that infections can occur once a person has been vaccinated against the coronavirus. “We will know what the answer is when we follow people longer,” he said in an interview on CNN.

For her part, the WHO chief scientist, Soumya Swaminathan, assured at a press conference that people vaccinated against the coronavirus can contract the virus and can spread it to others even if they do not get sick or have no symptoms. However, he pointed out that “if you have the vaccine and you contract the disease, the viral load is much lowerSo the chances of infecting others may also be lower.

Will I have to wear a mask after getting vaccinated?

As Swaminathan pointed out, until evidence is obtained to show that vaccinated people cannot pass the virus to third parties, it is necessary that all people who receive both doses of the vaccine against SARS-CoV-2 continue to use the mask and respect the rest of the security measures to avoid the spread of the virus.
