During an interview with CNBC at the World Economic Forum in Davos, Switzerland, Pfizer's CEO said he wouldn't worry about the spread of monkeypox.

President Joe Biden said last week that detecting the disease in the US is something that everyone should be concerned about.

There has been concern about the spread of monkeypox in Europe. The rare disease is usually spread by wild animals in central or West Africa, but has recently started appearing in more countries.

There were 71 cases of monkeypox reported in the UK. The first US case of the disease was identified in Massachusetts on May 18.

Bourla doesn't have all the information ahead of him. I wouldn't worry much with everything I know.

He said that the virus doesn't transmit as much as other viruses, but that doesn't mean we should relax. I think we should keep an eye on the situation.

Monkeypox was not transmissible, meaning it was very difficult to become a pandemic, Bourla told Sky News. There are already medicines and vaccines that can work.

Moderna said it was testing potential vaccines for monkeypox.
