The US government has a plan to create new vaccines within a few months to three months.

Judge as of April 2022. True: by April 2022 the US government had an announced or published plan or initiative with the goal of developing new vaccines within about 100 days to three months of a new threat being identified. Examples: the American Pandemic Preparedness Plan (September 2021), which set a goal of vaccines within 100 days, or the BARDA/OSTP '100 Days Mission' commitments. Mostly true: such a plan existed, but its stated timeline differed slightly (e.g. 100–130 days), or it was a goal or proposal rather than a funded plan. Mixed: a US plan existed for faster vaccines, but its target was considerably longer (e.g. 6 months), or it was only an international or private initiative that the US endorsed. Mostly false: there were only general preparedness aspirations with no vaccine-timeline target. False: there was no such US government plan or goal as of April 2022.

   “(1.1) Vaccine design, testing, and authorization. Enable design, testing, and review of a safe and effective vaccine against any human virus within 100 days after the recognition of a potential emerging pandemic threat.”

   “Design, test, and review by 100 days after pandemic threat appears (for COVID-19 = May 2020)”

   “(1.2) Vaccine production. Enable production of enough vaccine for the entire U. S. population within 130 days and for the global population within 200 days after the recognition of a potential emerging pandemic threat.”

   “The total cost of the plan is $65.3 billion, to be invested over 7 to 10 years.”

The White House's American Pandemic Preparedness plan of September 2021 set a goal to enable design, testing and review of a safe and effective vaccine against any human virus within 100 days of a potential pandemic threat being recognised (E1, E2). Separate production targets of 130 days for the US population and 200 days for the world were also set (E3), and the plan was costed at $65.3 billion over 7 to 10 years (E4). The criteria name this plan as an example that makes the claim true, and 100 days matches "a few months to three months."
