What a difference a year makes, right? I remember last year at exactly this time Governor Charlie Baker was warning of Massachusetts' first surge in coronavirus cases.

Within a year of the world's worst pandemic since the Spanish Flu of 1918, scientists have developed a vaccine that has a near 95% efficacy rate (Moderna, Pfizer).

As of Monday, any Massachusetts resident age 16 and older, is now eligible for the COVID-19 vaccine.

Side note...Baker will be here! on Thursday, according to berkshireeagle.com.

Starting this week, some Massachusetts locations of Walgreens, CVS, and Walmart will now start carrying home testing kits for COVID-19.

These will be available for purchase without a prescription.

Unlike the one that has been available for purchase, the two new kits will not be the lab-based PCR test. See below.

This PCR test is available now; however, the rapid antigen test is coming soon.

The new home test kits will be the antigen test, which are slightly less sensitive, according to yahoo.com.

Depending on the brand, one kit will cost $23.99, the other $38.99.

Both will have your test result within 15 minutes.

All stores should have the kits by May's end.
