Pretty soon, we are going to have a dozen vaccines and a great argument over which one is best. As with most medical things, the answer is “it depends…” humans are infinitely different and the introduction of a foreign substance will have an infinite number of consequences. Still, it’s good to have choices.
Moderna has been approved by the US government as the country’s second Covid-19 vaccine, clearing the way for millions of doses to be released.
The Food and Drug Administration (FDA) authorised the US-made jab about a week after approving a Pfizer/BioNTech vaccine which is now being distributed.
The US has agreed to purchase 200 million doses of Moderna, and six million may be ready to ship now.
