contact-tracing apps
7.1.The role of therapeutics
As stated by the WHO in its Covid-19 strategy update, it is 'ultimately the development and delivery
of a safe andeffective vaccine or vaccines and therapeutics that may enablea transition away from
some of the measures necessaryto maintain this state of low-level or no transmission'. Similarly, the
joint European roadmapto lifting coronavirus containment measures maintained that 'the
development of a safe and effective vaccine is crucial to help put an end to the Covid-19 pandemic'
and that 'societies will have to live with the virus untila vaccine or treatment is found'.
Given the great level of scientific activism and resource mobilisation, there is cautious optimism145
that there maybea Covid-19 vaccine sometime soon. The EMA estimates, however,that it could
take at least a yearbefore a vaccine against Covid-19 is ready for approval and then available in
sufficient quantities to enable widespread use.
The challenge relates not only to developingand testing a vaccine but also tomanufacturing and
distributingitto potentially billions of people who need it. According to Soumya Swaminathan, the
WHO chief scientist, in an optimistic scenario146theremay beenough doses of a vaccine next year
to immunise healthcare, followed by larger scale immunisation in 2022, though it might take four
to five years to inoculate the world. The concern with projecting unrealistically rosy timelinesfor
vaccines147is that this may soon provide ammunition to a growing number of vaccine-sceptics148
and may generally diminish publictrustand support for long-term containment measures.
Despite the great number of clinical trials, it is not clear when a Covid-19 treatment willbe available.
First of all, given the complexity of the virus, it is unlikely that a catch-all drugwill be able to tackle
all the effects of the disease. It is encouraging that there are so many candidates for Covid-19
treatments, although this variety may also be a sign of fragmentation, effort duplicationand,
generally, lack of coordination.149
7.2.The role of testing
The existence of appropriate monitoring capacity, which includes large-scale testing, is one of the
three criteria identified inthe joint European roadmapforlifting coronavirus containment measures.
The roadmap considers measures to expand testing capacity as aprecondition for lifting social
distancing measures. This includes rolling out serological testingto assess the acquired immunity
of the population and rolling out self-testing kits, 'once properlyvalidated and their reliability
ensured'. In its communicationon a phased and coordinated approach for restoring freedom of
movement and lifting internal border controls, issued on 13 May, the Commission stated that
restrictions on travel should first be lifted in areas with a comparable epidemiological situation,and
'where sufficient capabilities are in place in terms of hospitals, testing, surveillance and contact
tracing capacities'.
