About 41 West Virginian patients who earlier received the Regeneron monoclonal antibody treatment instead of the Moderna vaccine ultimately got their first shot of a vaccine Thursday, the West Virginia National Guard told ABC News.

The patients were among the 44 people who were identified on Dec. 31 as receiving the wrong treatment at a vaccination clinic hosted by staff at the Boone County Health Department.

The National Guard did not say which vaccine those patients received when they got the correct shot.

Their first shots come despite recommendations by the U.S. Centers for Disease Control and Prevention that patients who receive monoclonal antibodies or convalescent plasma should defer vaccinations for at least 90 days.

Pfizer and its partner BioNTech have plans to begin offering their COVID-19 vaccine to clinical trial volunteers who received placebo by March 1, several months earlier than initially planned, STAT reported.

The FDA and its advisers had pushed hard for volunteers to remain on placebo as long as possible to gather more safety and efficacy data about the vaccines, while the companies argued that volunteers should receive the vaccines sooner for both ethical and practical reasons.

340,000 people have been vaccinated to date in Texas, out of the state's received allotment of 786,000 vaccination doses, according to data from Texas Health and Human Services.

Houston Mayor Sylvester Turner also authorized the Houston Health Department to open the city's first free COVID-19 vaccination clinic on Jan. 2. The clinic will expand vaccine access to the general public at high risk of severe illness and death from coronavirus disease, according to a statement from Texas health officials.

Texas' health department received its first allotment of 3,000 doses of the Moderna vaccine and started administering it on December 28.

The Houston Health Department will announce additional free vaccination opportunities as supply increases.

New York has become the fourth state to cross 1 million COVID-19 cases, the governor announced Saturday.

New York joined California, Texas and Florida in hitting that mark. Illinois, at over 975,000 cases, is likely to join those four in the coming days. California has already crossed 2 million cases.

"With 2020 now behind us, we can see brighter days ahead, but to get there quickly, it's going to take all New Yorkers staying smart and staying united," Gov. Andre Cuomo said in a statement. "We have the vaccine, and that is good news, but it will be months before we've reached critical mass, making it as important as ever that we do not let COVID fatigue get the best of us."

The state reported just over 15,000 new cases on Saturday and a percent-positivity rate that has grown to 7.45%. That number was around 1% for much of the summer after being the epicenter for the pandemic in the spring.

There was some good news on Saturday as Cuomo reported there were 72 fewer people hospitalized due to the virus in the state.

Officials continue to fear growing cases in the new year after Christmas and New Year's travel in recent weeks. New York crossed 30,000 deaths earlier this week.
