There are some legit questions and concerns. I'm not an anti-vaxxer but asking some doesn't automatically make you an idiot. In fact, if you don't ask some of these, I think that makes you the idiot. This is from one mainstream media source, NBC:
Pfizer's Covid-19 vaccine promising, but many questions remain
Pfizer's vaccine is a new type of technology that's never been used in mass human vaccination.

1. New type of tech that has never been used on human vaccination before. "The caution is that this would be the first mRNA vaccine to be used in humans, so it's important to look carefully at the safety data."
2. "We don't know anything about groups they didn't study, like children, pregnant women, highly immunocompromised people and the eldest of the elderly," Dr. Gregory Poland, director of the Mayo Clinic's Vaccine Research Group in Rochester, Minnesota, said.
3. It is also important to get a sharper picture of Pfizer's claim of about 90 percent effectiveness. This first analysis only included data on 94 confirmed Covid-19 cases, meaning there is no proof yet that the vaccine prevented infection.
4. Dr. William Haseltine, an infectious diseases expert and president of ACCESS Health International, agreed with that assessment. He predicted that if the vaccine indeed is proven safe and effective, it may work more like the flu shot.
"It's not necessarily going to protect you from infection, and it may not work for everyone," Haseltine said Monday on MSNBC. "But it should be useful for many people. And it should moderate the severity of disease."
5. It's also uncertain how long such protection might last. That answer can only come with time, as it's impossible to know yet whether immunity remains for months, a year, two years — or a lifetime. (For comparison, flu shots are generally only about 50 percent effective, while measles vaccines are up to 97 percent effective.)
