Figure out if these mean better neutralization or worse neutralization:
# In 34 convalescent cases 4–9 weeks following infection in June 2020, before the emergence of B.1.1.7, neutralization titers
# against B.1.351 were, on average, 13.3-fold reduced compared with an early Victoria sample (p < 0.0001). Significantly, 18
# of 34 samples failed to reach 50% neutralization at a plasma dilution of 1:20, with a number showing a near total reduction of neutralization activity.
# In 13 convalescent cases 4–9 weeks following infection with B.1.1.7, neutralization titers
# against B.1.351 were, on average, 3.1-fold reduced compared with an early Victoria sample (p < 0.0001).

# Neutralization capacity GMT of 27 subjects' sera post-infection was considerably higher (stronger) than after the second
# Pfizer dose, and 4.5x drop in B.1.1.7 neutralization was observed.

# Neutralization capacity GMT of 27 subjects' sera post-infection was markedly worse against B.1.1.7 + E484K than the lineage alone, with a 11.4x drop.

# In convalescent sera one month or more post-infection in Spring 2020, an average 6.5x decrease in reciprocal ID50 value was observed
# ten key point mutations in Spike in the P.1 lineage vs wildtype. A 3.4x decrease against the full P.1 type vs WA-1 was observed, with
# better full P.1 ID50 reciprocal value compared to the 10-mutation model.

# In a Syrian hamster model, B.1.351 variant virus had >4x reduction in YRNT90 (measure of neutralization) using wild type convalescent sera.
# PG: Note that exact sequence for B.1.351 used was not disclosed.
