I’m doing a summary about the Pfizer vaccine, how it works, who should it get it first and how long it lasts, so if you can help me write the best essay title for it. Thank you in advance?

One of the difficulties about writing a summary of any of the vaccines for the novel Coronavirus that is known as COVID-19 is that much of the information remains unknown.  In addition, because the vaccines created by Pfizer and Moderna are both mRNA vaccines, which are not a familiar type of vaccine, they create some additional questions.  How long will the vaccines be effective?  Are they safe?  Will they work to prevent infection by the newer strands of COVID-19?  Do they change your DNA as some people on the internet are suggesting?  You probably want to address all of those topics in your summary, even if some of the answers are going to have to be that scientists do not know the answers at this time. 

Here are some essay title suggestions:

1. Stopgap or Savior: What the Pfizer Coronavirus Means for the Worldwide COVID-19 Pandemic
2. The Differences Between DNA and mRNA: Why the Pfizer COVID-19 Vaccine Will Not Alter Your DNA
3. Double Your Protection: Taking the Second Dose of the Pfizer COVID-19 Vaccine Offers Almost Twice the Protection as a Single Dose
