A sub-analysis from the Oxford-led COV001 and COV002 trials with Vaxzevria induced strong immune responses following either a prolonged second dose interval of up to 45 weeks or following a third boosting dose.
Oxford-led COV001 and COV002 trials showed that Vaxzevria induced a strong immune response following a long second dose interval (up to 45 weeks) and after a third booster dose.
Interim results from the ongoing Phase I/II COV001 trial, led by Oxford University, showed AZD1222 was tolerated and generated robust immune responses against the SARS-CoV-2 virus in all evaluated participants.
