COVID-19 . . . Evidence that a Vaccine is Possible

(Disclaimer: The World Health Organization <WHO> has officially named the new coronavirus as SARS-CoV-2 and the disease it causes as COVID-19.  Because the majority of people, including much of the press, commonly refer to the virus as “COVID-19,” to avoid confusion, I use COVID-19 as the name of the virus in these posts.)

COVID-19

The 100+ labs trying to develop a vaccine for COVID-19 were delighted with a study showing that COVID-19 stimulates a strong antibody response in humans. Scientists from the University of California at San Diego (UCSD) demonstrated that a vaccine for COVID-19 is definitely possible.

The scientists studied blood from mildly sick individuals who recovered. They found a high level of antibodies to the spike protein, used by COVID-19 to infect.

The strong antibody response suggests that immunity will occur in humans and will last a while, but no one knows for how long – weeks? months? years?

The scientists were surprised by another result. For you also to understand it, I have to give you some background. (Sorry!)

There are seven coronaviruses that infect humans.

Four are common and cause mild, cold-like symptoms.  We’ve all probably had one or more of these.

Three coronaviruses (SARS-CoV, SARS-CoV-2 <which causes COVID-19>, and MERS- CoV) cause serious human disease and some fatalities.

Blood taken before COVID-19 even existed in humans nevertheless showed the presence of antibodies that reacted with COVID-19.  Infection with one of the mild coronaviruses may have stimulated the body’s production of some antibodies that cross-react with COVID-19.

Some seemingly healthy individuals have died from COVID-19. In contrast, some people not predicted to do well had mild disease or were asymptomatic. Doctors are perplexed by their inability to predict who will recover.

One possibility is that the amount of cross-reactive antibodies arising from previous infection with one or more of the mild coronaviruses may determine how well a COVID-19-infected person will do.

 

Stay Safe and Healthy!
