With the entire population slated to hopefully receive the vaccine, and with people suffering from various ailments at any given time, the coincidence of someone receiving a vaccine near the time some other health event happens is probably higher than 1 in a million. Determining if these clots are coincidence or an extremely rare yet treatable side effect is going to slow a lot of people from getting the much-needed vaccine. Being aware of the clotting issue and the treatments (and if someone begins to have a problem get a blood test and find out about the platelets) seems a prudent warning label, but please, go ahead and give the vaccines. Far more people will die of COVID if they don't receive it. The odds are working against those who might get clots, so be vigilant, but get the vaccine.
