Are We Getting Closer To A Vaccine Or Drug

Coronavirus is spreading around the world, but there are still no drugs that can kill the virus or vaccines that can protect against it.

So how far are we from these life-saving medicines?

What sort of progress is being made

Research is happening at breakneck speed, and there are more than 20 vaccines currently in development. Among those under way at the moment are:

  • The first human trial for a vaccine was announced last month by scientists at a lab in the US city of Seattle. They have taken the unusual step of skipping any animal research to test the vaccine’s safety or effectiveness.
  • Australian scientists have begun injecting ferrets with two potential vaccines. It is the first comprehensive pre-clinical trial to move to the animal testing stage, and the researchers say they hope to move to the human testing stage by the end of April.Tests like these are taking place much quicker than would normally be the case, and some are using new approaches to vaccines. It follows that there are no guarantees everything will go smoothly.
  • Could existing drugs treat coronavirus?

    Doctors are testing current anti-viral drugs to see if they work against coronavirus. This speeds up research as they are known to be safe to give to people.

    Trials are taking place in England and Scotland on a small number of patients with an anti-viral called remdesivir. This was originally developed as an Ebola drug, but also appears effective against a wide variety of viruses.

    Similar trials have already been carried out in China and the US, and results are expected in the next few weeks.

    There was much hope that a pair of HIV drugs (lopinavir and ritonavir) would be effective, but the trial data is disappointing.

    They did not improve recovery, reduce deaths or lower levels of the coronavirus in patients with serious Covid-19. However, as the trial was conducted with extremely sick patients (nearly a quarter died) it may have been too late in the infection for the drugs to work.

    Studies are also taking place on an anti-malarial drug called chloroquine. Laboratory tests have shown it can kill the virus, and there is some anecdotal evidence from doctors that it appears to help. However, the World Health Organization says there is no definitive evidence of its effectiveness.

    Remember, there are four coronaviruses that already circulate in human beings. They cause the common cold, and we don’t have vaccines for any of them.
