Moderna has signed an additional agreement with Taiwan to supply 20 million doses of its Covid-19 vaccine and updated variant booster vaccine candidate, if approved.

The European Medicines Agency has listed Guillain-Barré syndrome, a neurological disorder, as a very rare side effect of Johnson & Johnson (J&J)’s Covid-19 vaccine. As of 30 June 2021, 108 cases of the disorder have been reported among more than 21 million individuals who received the vaccine. A review by the agency’s safety committee found the possibility of a causal relationship between the vaccine and the disorder. Meanwhile, a US Centers for Disease Control and Prevention advisory panel said that the benefits of the J&J shot outweigh its risks.

New research by the University of Oxford, the World Health Organisation and the United Nations Development Programme has revealed the urgent need for Covid-19 vaccine equity to avoid a “lasting and profound impact” on recovery in low and lower-middle income countries. As per the study data, high-income countries could vaccinate faster and have a quicker socio-economic recovery while low-income countries might not reach growth of pre-Covid levels until 2024 without cost-effective and accessible vaccines.
