US President Donald Trump on Monday hailed new guidelines as he said he is confident the new vaccine can be used at hospitals and clinics after nearly eight months of what a government health official called a “delicate process” with “a difficult road ahead”.

President Trump commended Dr. Tom Frieden, director of the Centers for Disease Control and Prevention (CDC), at an event on the administration’s commitment to vaccinating all Americans against the dangerous H1N1 flu virus, the official said.

“I have had a wonderful working relationship with Dr. Frieden,” Trump said. “I said, ‘You can have the vaccine. We all can have the vaccine. You get on with life. You make the best food in the world, people will know what you do.’ I’ve been very, very, very, very, very honored by the good work that he’s done.”

While most healthcare workers believe that producing and distributing the new vaccine would not pose a risk to patients, others are concerned about the safety of the vaccine given that it contains synthetic sterols – a chemical similar to the chemical compound from which the dead virus is derived.

Trump confirmed that while the new vaccines won’t cause illnesses at home or in the United States, they could trigger a “great flu pandemic”.

Responding to President Trump’s comments, Dr. Frieden told reporters he hoped the US government “will make the right decision” about distributing the new H1N1 vaccines.

“This is a complex package of new vaccines and also a supplement to existing existing vaccines,” Dr. Frieden said. “It has taken over eight months to get this right, and we have lots of work ahead to make sure that we protect the most vulnerable.”

While I believe that this is the only reform of the vaccine protocols that can be successfully done, it is important to be clear. I will work with my colleagues to make sure the next wave of #H1N1 vaccination is safe, and effective for the American people. — Donald J. Trump (@realDonaldTrump) September 16, 2018

As Trump commended Frieden and his team, Rep. Kevin Yoder (R-Kansas) pointed to the man in charge of dealing with this issue.

“What Dr. Frieden demonstrated was that, unlike in the past when it took years of work and effort to get H1N1 vaccines to the American people, we were able to get this vaccine rolling so quickly that it is delivered to millions and millions of children in just a few weeks,” Yoder said.

The 3 to 6 dose flu vaccine that’s in the flu vaccine will be considered for use in hospitals and clinics across the United States for next few weeks, an HHS official said.

The shots will be given along with flu virus shot to about 2 million U.S. households in October, said Mike Mason, communications director for the national influenza division of the CDC. In addition, about two million influenza vaccine doses will be administered by the federal Food and Drug Administration.

States and health departments will distribute the shots. States can decide whether or not to rely on the federal government to distribute the shots, Mason said. States can decide to give the shots as part of their Medicaid programs or another program for the uninsured. The CDC’s blueprint said the Centers for Disease Control and Prevention in Atlanta will help administer the shots.

In Texas, researchers are conducting a public health experiment to test whether the new vaccine will function better in the elderly and pregnant women. Pennsylvania and New York have also approved the use of the new vaccine, as have some eastern states. State officials have reported that anecdotal reports of people experiencing flu-like symptoms to the CDC after receiving the new vaccine have been replaced by reports of severe effects when vaccinated themselves.
