Vaccinated people can be carriers of the coronavirus – Diseases

Experts in the United States have found that vaccinated people can be carriers of the coronavirus. Pfizer and Moderna are investigating how many of those vaccinated can transmit the virus.

Even if you have a coronavirus vaccine, you cannot go without a mask in public. This is the opinion of the doctors for now. The nose is the main source of viral infections. Including the coronavirus. There it multiplies rapidly and activates the immune system, but coronavirus vaccines are injected into the muscles. The vaccine stimulates the production of antibodies and this should be sufficient protection to prevent the person receiving the vaccine from getting sick. Some of the antibodies can circulate in the blood to the nasal mucosa and protect against infection.

But it is not yet clear whether they will be enough and how quickly they can be mobilized. If there are not many, viruses can flourish in the nose and sneeze or exhale and infect others.

It’s a race, depending on whether the virus can be produced faster or if the immune system can control it faster, says Marion Pepper, an immunologist at the University of Washington in Seattle.

That’s why vaccines that are injected into the nose as a spray or given by mouth are better than intramuscular injections for respiratory viruses, experts say.

For those vaccinated against Covid-19, the use of masks has yet to be phased out, BNR explains.
