New Hampshire is opening two more walk-in COVID-19 vaccination sites this week and has plans to open more, Gov. Chris Sununu said Wednesday.A new location has opened in Stratham, and a site will open Friday in Concord, Sununu said. There are already five state-run walk-in locations open.>> Latest COVID-19 impact coverage from WMURThe governor said other locations will open next week in Manchester, Nashua and Salem, and a location in Keene should open by the end of the month.Vaccination rates have been mostly flat in New Hampshire since the summer, but Sununu said vaccines remain the best tool available to fight the pandemic.>> COVID-19 in New Hampshire: Important information"That doesn't mean we're going to sell ourselves short in terms of trying to promote it and make it available," Sununu said. "A lot of health care facilities are pulling back a little bit on themselves doing the vaccine, so again, we'll try to take the burden off them a little bit and allow them to focus a little bit more on their patients."While the omicron variant of COVID-19 spreads more easily than previous variants, research has shown that those fully up-to-date on vaccinations, including booster shots, are much more protected against hospitalization and death.New Hampshire is also working to increase the availability of at-home COVID-19 tests. Sununu said he's planning to ask lawmakers for $10 million to buy at-home tests that will then be distributed by the state.Granite Staters have been able to request at-home tests from the state twice, and the federal government launched its own site to request free tests Tuesday. Sununu said the at-home tests have been tough to find, and there's no guarantee that New Hampshire will be able to immediately locate enough tests to distribute.Sununu praised the federal site and urged people to order their tests. He said at-home tests are increasingly valuable to let people know when they have the virus and when they can return to work or school."We urge people to watch for symptoms, watch closely," Sununu said. "Anyone sick needs to remain home."When it comes to state-run PCR test sites, getting quick results remains an issue."We're pushing on those contractors as best we can," Sununu said. "I don't know of any testing facility that isn't just all out 24-7 trying to keep up with the demand right now."Sununu also announced that a third strike team will be added by early February to help a long-term care facility in Portsmouth. He said supporting such facilities helps hospital capacity by allowing them to more easily move patients.** Town-by-town: COVID-19 case data | Vaccination data **--
