Why do everyday masks work as a vaccine against Covid-19?


Professor Monica Gandhi of UCSF (University of California, San Francisco) formulated the result of her research in the form of a question: “Could wearing a mask be a gross vaccination until we have a real vaccine?” And the researcher explains her theory of containing Covid-19 in a few words: Wearing masks decreases the viral load – which spreads – and increases asymptomatic infections. Asymptomatic infection leads to stronger T cells and, at times, immunity to the coronavirus.

Monica Gandhi and George W. Rutherford wrote their theory published in the “New Englang Journal of Medecine”.

To this end, we can imagine that everyone is sitting on a bus or subway, or shopping in the supermarket, wearing everyday masks. Anyone who wears a mask and meets someone who is infected with SARS-CoV-2 is exposed to only a small amount of viral inoculum – i.e. thanks to the masks only a small amount of virus.

If the theory is confirmed that people exposed to lower viral loads also get less sick, it may lead to a mild immune system reaction or illness.

After that, the person concerned is immune to the coronavirus – at least for a certain period of time.

In a September 1 tweet, Monica Gandhi sees her theory confirmed by the recent high number of low mortality cases in Spain, where a mask is mandatory in many places. The scientist from San Francisco assumes that many people there are already immune to the corona virus.

Monica Gandhi also writes: “Ultimately, fighting the pandemic is about reducing both transmission rates and the severity of the disease. Growing evidence suggests that wearing a mask in general could serve both purposes. “
