  • Monitoring the Results and Side-Effects – The government has asked all the vaccine manufactured companies to keep track of the results of the vaccine. There might be side effects that did not get noticed during the trials. FDA and CDC are expanding their vaccine monitoring work so they can find the side-effects and results early.
