The quickest way to end the Covid-19 pandemic is by reaching herd immunity, which is to say, getting enough people immune to the disease that it no longer spreads easily, thus protecting everyone, including those few who still haven't acquired immunity. Typically, there are two ways to reach herd immunity: mass vaccination programs, which have effectively eradicated many deadly diseases in the U.S. (e.g., small pox, tetanus, polio, diphtheria) and mass infection. Problem is, unlike influenza, chickenpox, mumps, measles and many other familiar diseases, Covid-19 infection does not appear to produce long-lasting or robust immunity, meaning people could, theoretically, catch it multiple times and continue spreading it through the community. This leaves mass vaccination as our best hope.
Anthony Fauci said he was cautiously optimistic that by the end of 2020, we would have data confirming that at least one of the current vaccines being tested for Covid 19 was safe and effective. In theory, that could mean we'd have enough doses by mid-2021 to vaccinate a sufficient number of Americans to reach herd immunity, thus bringing an end to the pandemic. (For the current status of vaccine trials, click here).
Problem is, 20% of Americans say they will refuse to take the vaccine, and another 31% say they are unsure. So, even if the vaccine was 100% effective (no vaccine is), that would mean only 49% of American would develop immunity, which is not enough to reach herd immunity. Consequently, the virus would continue to spread through communities, sickening and killing people. In reality, a vaccine could be approved if it is at least 50% effective. So, worst-case scenario, we get a 50% effective vaccine, with only 49% of Americans taking it, and we end up with only 24.5% immunity, far far away from the 60-75% needed to reach herd immunity.
While it is easy to disparage these anti-vaxxers as stupid or selfish (the behavior certainly is), doing so won't browbeat or shame them into changing their behavior and is, therefore, unproductive. And at this critical time, it is imperative to find solutions that are effective. If the 31% of Americans who are on the fence can be convinced to change their minds, we'd have 80% of Americans willing to take the vaccine, and that COULD bring us to herd immunity (assuming the vaccine was 75% effective).
Part of the problem, of course, is STUPID and SELFISH behavior by politicians, particularly Trump, which have contributed to the misperception that this disease is not that serious or that it's a hoax. As long as people believe this, why should they want to do anything inconvenient or unpleasant (like wear masks & socially distance themselves), or that they erroneously believe is risky (like get vaccinated)? So, the first challenge will be getting all leaders and media to start listening to, respecting and complying with the health experts and encouraging the rest of us to do so, too.
However, there were already plenty of Americans who were terrified of vaccines well before the current pandemic started. So, even if all leaders were to suddenly start wearing masks and telling everyone to comply with social distancing policies, these people might still refuse to take the vaccine, thus perpetuating the pandemic. Therefore, we also need a well-researched and well-executed public health campaign that acknowledges their fears, but then convinces them of the safety of the vaccines and encourages them to participate in the mass vaccination program, not only for their own health and safety, but because it will help end the pandemic and return us to normal more quickly.
