I’ve heard experts mention a 12-18 month timeline. Maybe 3 months for phase 1 (make sure the vaccine itself doesn’t cause harm), maybe 6-9 months for phase 2(make sure it works), then another 3-6 months to roll it out on a larger trial.No.
1- that some are being tested does not mean “there is a vaccine”, which implies it works. Most vaccines, drugs, and biologicals that are tested don’t work and fail or are shown to not be safe.
2- it takes much longer than 3 months!!! Average time for a drug is 7 years. Even for rare serious diseases with no treatment options (where the FDA will work with you more), it is still at least 2-3 years. Vaccines can probably be faster. But I don’t think 3 months, or even 6.
Even once you are ready for safety and efficacy studies in humans, you have to design the trial, enroll the subjects, collect and analyze the data, write the report, send to the FDA for their review and approval. And then you have to manufacture it. Each step takes time. Patient safety in trials is a big deal!
The vaccine has to be right. You don’t want to give people a false sense of security and make the spread worse.
I expect to see something available a little sooner in Europe because they seem to have looser standards. Though, I do think the FDA will let this move a little faster than normal.
