He said he and his friend were offered the vaccine because health care workers did not come to their appointments to receive the doses.

A Washington law student recently got more than groceries during a supermarket trip after accidentally receiving a Covid-19 shot.

David MacMillan and his friend were at a giant food store in the U.S. capital last week and were surprised when a worker in the supermarket’s pharmacy department offered them a shot each.

Getting a vaccination wasn’t on the couple’s shopping list yet, and right now the vaccine is being prioritized for rescue workers and other frontline workers.

MacMillan posted a replay of getting the shot on TikTok, where it was viewed more than 700,000 times on the short-form video-sharing platform as of Monday.

He said he and his friend were offered the vaccine because health care workers did not come to their appointments to receive the doses.

The Moderna vaccine must be kept in very cold temperatures and will spoil quickly once it’s taken out of the freezer and its lid pierced.

“It’s important for people to see that this is a good thing when there is so much misinformation swirling that this is a positive thing. We should look forward to dealing with the pandemic, ”MacMillan told a local NBC News partner.

The introduction of vaccinations in America has started more slowly than expected. So far, 4.2 million people have received their first doses of two-dose vaccines from Pfizer-BioNTech or Moderna – well below the official projections of 20 million by New Year.

MacMillan said he expected to have the second dose of his vaccination later this month.

In a statement, Giant said, “The Moderna vaccine is valuable and life-saving, and we’re glad we didn’t waste it and gave this couple doses each.”
