国会疫苗调查委员会要求辉瑞2/1之前就如何研究新疫苗做出解释

This morning I sent a letter to @pfizer demanding a FULL EXPLANATION on how they’re developing new vaccines. Creating new virus variants to sell vaccines is EXTREMELY unethical, and should NEVER be allowed. I'm expecting a full response from @pfizer NO LATER than February 1st.
