A better question - is it safe to get ANY of the vaccines yet?
It is a simple question of evolution. Those who get a vaccine and live to reproduce will pass their genetic structure on to the next generation. Those who get the vaccine and then die from the vaccine will not pass their genetic code into the future. Eventually, the genes for living with vaccines will predominate. Evolution: a process to adapt to new paradigm and attempt to flourish. Those who do not successfully adapt may wind up discontinued.
Get all them and report back
Well we have about 10 months of safety data from clinical trials saying it's safe. And between Moderna and Pfizer's Phase 3 trials in just the US and the UK, over 100,000 people showed the vaccines are safe and effective. By now, 131 million doses of COVID-19 vaccines have been given worldwide. Rare allergic reactions (about 1 per 100,000 people for Pfizer and about 1 per million people for Moderna) have been observed, but those are quickly treated, typically with a shot of epinephrine to reverse the reaction.
So far, all evidence points to these vaccines being very safe and extremely effective.
