A Coronavirus Vaccine in Months? Not So Fast, Scientists Say.
President Trump’s Operation Warp Speed panel hopes to make a Covid-19 vaccine available ”by the end of the year if we can, maybe before.” Many scientists are skeptical. The history of vaccines suggests it could take much longer.
The mumps vaccine is thought to hold the record for shortest turnaround: four years. When researcher Maurice Hillleman’s daughter contracted the virus in 1963, he took a throat swab to his lab. A vaccine based on the “Jeryl Lynn” strain was approved in 1967.
Some newer vaccines have been decades in the making. The chickenpox vaccine, approved in 1995, took 28 years to develop. The 2006 HPV vaccine took 15. Testing for safety and effectiveness, manufacturing millions of doses and regulatory review all take time.
Researchers have been trying to create an HIV vaccine for nearly 35 years. While medications have been developed to help people manage HIV and AIDS, there is still no vaccine.
Today, there are over 100 Covid-19 vaccines in development around the world. At least eight are being tested on people, including one with encouraging early results from the drug maker Moderna. Will the crisis create a record breaking vaccine? Time will tell.
