According to the researcher, whenever the number of infected people is so high, it is recommended to wear the mask even after vaccination.

Coronavirus – the second year

It has been more than a year since the Chinese authorities informed the WHO of the emergence of a new, rapidly spreading virus. Since then, there has hardly been a person in the world who has not heard the term Covid-19, and more and more people are mourning a family member or friend with whom the new disease has ended while stocks have collapsed in weeks. and all of our lives. they have been rewritten by the epidemic. By now, the vaccines have been completed, which in turn raises not only hope, but again many questions, while not only stopping the virus, but also threatening another mutation. You can find the details of this fight in our series of articles.

No Covid-19 vaccine protects against infection, only illness caused by the virus, especially hospitalization, Katalin Karikó told I Love You Hungary.

“Antibodies that circulate in the blood and memory cells cannot prevent the virus from multiplying in the cells of the nasal and oral mucosa. There is data on the Pfizer vaccine, which shows that it reduces the chances of infection by 30% and that the infected and vaccinated person transmits less virus. Said the Hungarian researcher residing in the United States.

He also said that not a single Covid-19 vaccine protects against the disease 100%, and even the most effective mRNA vaccines, Pfizer and Moderna, have protected vaccinated people 95% from symptomatic disease.

Karikó stressed that it is recommended to wear the mask even after vaccination, as long as the number of infected is so high. On the one hand, to prevent the vaccinated from becoming infected, or if it is infected, not to transmit it.

According to the researcher, it is not true that there are more and more mutants due to vaccines.

Katalin Karikó cites an article published in the New England Journal of Medicine that says that the appearance of the variants is not caused by vaccines, but by infections in people who have been subjected to immunosuppressive therapy.

“The article describes the medical history of a 45-year-old patient who was subjected to immunosuppression due to an autoimmune disease and became infected with the coronavirus. The patient had a positive Covid test for five months because his weakened immune system could only partially fight the virus, it could not defeat it. As a result, more and more variants of the virus developed in his body, eventually leading to the death of the patient. “He said.

According to Katalin Karikó, this is the reason why vaccination is important so that the virus does not have the possibility of creating mutants.

Those who became infected after vaccination also thought they might have contracted the virus because they had not received the correct dose of the vaccine.

The biochemist didn’t believe this, he said, at a much lower dose during the clinical trial. Katalin Karikó said they do not yet know if a revaccination is necessary and, if so, for how long.
