South Africa has approved a clinical trial for a COVID vaccine pill, Israeli pharmaceutical company Oramed said on Friday.

Its majority-owned subsidiary Oravax Medical has received clearance to begin enrolling patients in the trial of an oral vaccine, the company said in a statement.

South Africa has hosted several COVID vaccine trials. This will be the first for an oral approach.

Oral vaccines are particularly attractive for the developing world because they reduce the logistical burden of immunisation campaigns, the company said.

But they could also increase uptake in wealthy countries where needle aversion is an often missed factor in hesitancy.

“They do not require a medical professional to administer,” the company said in a statement. “They are more desirable to the potential recipients because they do not involve injections.”

A vaccine pill could become especially attractive if ongoing boosters are required.
