Another experimental covid-19 vaccine has shown promising early results

The news: An experimental covid-19 vaccine being developed by Pfizer and BioNTech provoked immune responses in 45 healthy volunteers, according to a preprint paper on medRXiv. The levels of antibodies were up to 2.8 times the level of those found in patients who have recovered. The study randomly assigned 45 people to get either one of three doses of the vaccine or a placebo. But there were side effects like fatigue, headache, and fever—especially at higher doses. The researchers decided to discontinue with the highest dose, 100 micrograms, after the first round of treatments.

This was a Phase I test: small group, multiple dose levels to determine where significant side effects start happening and whether lesser doses produce desired antibodies. The Feds invested $$ early, January and February, and have greased the bureaucratic wheels, and multiple companies have treatments and vaccines well into the testing process.

Aren't those precisely the symptoms of the virus?

Yes, but they are also a sign that the immune system is kicking into gear and making antibodies to fight something.
