Here’s Why You Should, Wear a Mask, After Getting Vaccinated.br As COVID-19 vaccines roll out across the world, many peoplebr are wondering what that means for current mask-wearing protocols.br Although vaccines are proven to prevent serious illness,br it’s unclear whether they completely curb COVID-19 infection.br It’s possible that some vaccinated peoplebr could still be silent spreaders of the virus.br When it comes to respiratory infectionsbr such as COVID-19, the nose is a main pointbr of entry into the human body.br Viruses rapidly multiply in the nose andbr prompt the immune system to producebr antibodies specific to mucosa.br Mucosa is a type of moist tissue that is unique tobr your nose, mouth, lungs and stomach. .br If exposed to the virus a second time, thosebr antibodies are able to shut it down in the nose beforebr it has the chance to travel deeper into the body. .br This is why mucosal vaccines, such as FluMist, arebr more effective at fending off respiratory viruses. .br The current COVID-19 vaccines are notbr mucosal. They are injected deep into a person’sbr muscles to stimulate an immune response.br This protects the vaccine recipient from getting ill, br but the virus could still bloom in the nose and be br sneezed or breathed out onto others. .br Preventing severe disease is easiest,br preventing mild disease is harder, andbr preventing all infections is the hardest …br If it’s 95 percent effective at preventingbr symptomatic disease, it’s going to bebr something less than that in preventingbr all infections, for sure, University of Arizona Immunologistbr Deepta Bhattacharya, via ‘The New York Times’.br Moderna and Pfizer are currently examiningbr past participants in order to determine whether they becamebr infected with COVID-19 after receiving the vaccine.
