Moderna’s Booster Shots
Appear ‘Effective’ at Protecting
Against COVID-19 Variants.
On May 5, Moderna reported results from its ongoing
studies involving booster doses for its COVID-19 vaccine. .
Current research suggests that people who've received Moderna's existing vaccine have a diminished response to variants. .
The drugmaker disclosed data from
two of its three strategies. .
One strategy involves administering a third shot containing
half the dosage of its current vaccine. .
The other involves administering a third dose
containing a completely new vaccine developed specifically
to protect against the South Africa variant. .
According to Moderna, both boosters displayed
protection against variants that was “similar to or higher”
than the peak protection its original vaccine offered
against the first strain of COVID-19.
In particular, the specialized-vaccine
booster appeared to be “more effective” at protecting
against variants than the half-dosage booster. .
“Solicited adverse events” following
the booster shots were found to be
“mild” or “moderate.”.
The most common side effects were
injection site pain, fatigue, headache,
muscle pain and joint pain.
Moderna’s Phase 2 study is ongoing.
Phase 3 data is expected to be
released in the coming months.
