A coronavirus vaccine won’t be widely available for a long time, several top pharmaceutical executives said Wednesday.

President Trump is pushing drug makers to develop vaccines swiftly, asking pharmaceutical executives on Monday if it could ready in the next few months. His comments came days after Dr. Tony Fauci, director of the National Institute of Allergy and Infectious Diseases, said a vaccine would hopefully be ready if the virus returns next year.

Johnson & Johnson will likely start phase one trials by the end of this year and begin larger-scale trials next year, said Paul Stoffels, the drug maker’s chief scientific officer.

Some outbreaks, such as Zika, disappear while vaccines are still in the clinical trial stage, Stoffels said.
