Boston (SmartAboutHealth) - The largest drug store in the United States has announced that by the end of the year, they will offer the H1N1 vaccine.

Walgreens made the announcement on Wednesday of this week, stating that they will have the H1N1 vaccine available nationwide in select locations.

The company already has begun to offer the vaccine at several pharmacies, but plans to expand greatly. This is great news as the H1N1 vaccine has begun to become far more widely available.

Walgreens and rival pharmacy CVS offer the H1N1 vaccine currently in 20 states, but that will expand to every state in the country soon.

Rite Aid is soon to follow as well as all of the big drug stores look to get on board to distribute the H1N1 vaccine.

The expectation is that by distributing the H1N1 vaccine, it will prove to not only help the general public, but also help the companies as a whole.

The demand for the H1N1 vaccine continues to outstrip the supply, but hopefully things will change for the better with this move by Walgreens.
