Vaccine expert Peter Hotez says Pfizer vaccine creates new challenges

Buzzkill Alert – Dr. Peter Hotez serves a test tube full of very cautious optimism about Pfizer’s huge coronavirus vaccine announcement.

The famous vaccine expert joined “TMZ Live” on Monday to explain exactly what it means to you, the Pfizer IF vaccine can really be 90% effective in preventing coronavirus infections.

First of all … Professor Hotez points out all the promising information comes from a company press release, and other scientists – outside of Pfizer – haven’t had a chance to confirm the data.

Assuming it’s correct, he says that we are now in uncharted territory for a vaccine in terms of technology, and that there are many other complicated variables in its production and distribution to the population. For example, it should be stored at -94 degrees Fahrenheit !!! No simple task for your average pharmacy.
