Wataalamu wa Afya kutoka Chuo Kikuu cha John Hopkins wanasema utengenezwaji wa haraka wa chanjo za COVID-19 haumaanishi kuwa hatua za usalama zilirukwa
Teknolojia zinazotumiwa kutengeneza chanjo hizo zimekuwa zikitengenezwa kwa miaka mingi ili kujiandaa na milipuko ya virusi vya kuambukiza
Serikali zilitoa pesa kwa watengenezaji chanjo mapema na hivyo kampuni kupata rasilimali walizohitaji kwa wakati

How was the COVID vaccine developed so quickly?
The relatively quick development of these vaccines does not mean safety measures were skipped. There are several reasons why the COVID-19 vaccines were developed faster than other vaccines:
The technologies used to develop the COVID-19 vaccines have been in development for years to prepare for outbreaks of infectious viruses. The manufacturing processes were ready very early in the COVID-19 pandemic.
Countries shared genetic information when it was available about SARS-CoV-2, the coronavirus that causes COVID-19, which gave vaccine developers an early start at finding a vaccine.
The testing processes for the vaccines didn’t skip any steps, but the vaccine developers conducted some stages of the process simultaneously to gather as much data as quickly as possible.
Governments gave money to vaccine developers in advance, so the companies had resources they needed.
Some types of COVID-19 vaccines were created using messenger RNA (mRNA), a new technology that allows a faster approach than the traditional way vaccines are made.
Social media enabled companies to reach out to and enroll study volunteers, and plenty of people wanted to help, so there were enough research participants to test the COVID-19 vaccines.
Because SARS-CoV-2 is so contagious and widespread, many volunteers who got the vaccines were exposed to the virus, and with so many exposures, it took a shorter time to see if the vaccines worked.
Companies began manufacturing vaccines ahead of their authorization or approval so some supplies would be ready if authorization occurred.
